Overview
The onsemi GBU6A is a single-phase bridge rectifier from the GBU6K series, designed for through-hole mounting in the GBU-4 package. It features a peak repetitive reverse voltage (Vrrm) of 600 V and a maximum average forward rectified current (If) of 6 A. The device supports a peak non-repetitive forward surge current (Ifsm) of 175 A and exhibits a maximum forward voltage drop (Vf) of 1 V at rated current. Operating temperatures range from -55°C to +150°C, with a maximum power dissipation of 12 W.
Feature Summary
- Robust surge current handling capability suitable for high-inrush applications
- High thermal stability allowing operation up to 150°C junction temperature
- Low forward voltage drop for improved energy efficiency
Applications
- General-purpose AC-to-DC power supply circuits
- Battery charging systems
- Industrial power conversion equipment
Procurement Notes
Verify the specific suffix against official datasheets to confirm voltage ratings, as variations exist within the GBU6K family. Ensure the procurement specification matches the required 600 V rating for the GBU6A variant. Confirm RoHS compliance status via the manufacturer's latest documentation before finalizing orders.
Selection Notes
Select the GBU6A when a 600 V blocking voltage is required for 6 A continuous current applications. Compare thermal resistance values against the system's heat sinking capabilities to ensure the 150°C limit is not exceeded under worst-case load conditions. Verify that the GBU-4 package dimensions fit the target PCB layout constraints.
Part Context
The GBU6A belongs to the GBU6K series of bridge rectifiers manufactured by onsemi. This series utilizes silicon planar technology for reliable performance. The component is distinct from other variants in the same package based on its specific 600 V reverse voltage rating, differentiating it from higher or lower voltage versions like the GBU6M or GBU6G.
Replacement Considerations
Cross-reference with other manufacturers offering GBU-4 packaged 6A/600V rectifiers. Ensure pinout compatibility and equivalent electrical parameters such as Vf and Ifsm are met. Verify that any substitute part holds necessary safety certifications if used in regulated environments.
